The Banksy Spy Booth mural in Cheltenham belongs to the Secretary of State for Transport rather than the owner of the house it is on, it is being claimed.
A retired chartered surveyor believes the wall is owned by the government but the homeowner, who is trying to sell the artwork, is seeking legal advice.
